the subdorsal and spiracular lines 
a similar row of smaller spots and 
tufts. Spiracular line, indistinct 
anteriorly olive, posteriorly dull 
yellow. Spiracles, biack. Head, red- 
dish yellow. Belly, dirty greenish 
olive, destitute of markings. Hatched 
the beginning of June. Full fed, 
middle of July. Pupa pale straw 
colour. Along the centre of both 
thorax and abdomen a double row 
of largish black spots; on each side 
three similar rows, the intermediate 
row much smaller than the other 
two. Upper border of wing-cases 
black. On the head or extreme end 
of the thorax two transverse black 
bands. Suspended by a thread across 
the junction of the thorax and ab- 
domen. In form, colour, and general 
appearance, closely resembles the 
pupa of J/, Artemis, the “ Greasy 
Fritillary.” In hot summers there 
is a second brood of this butterfly 
in September. The year before last 
I fed up a batch of larve in July, 
and every pupa emerged in Septem- 
ber. H. HARPUR CREWE.

Wuite Sanp Marri. — On the 
20th of August last a White Martin 
was shot by Mr. F. Wheeler, on the 
Thames, near Marlow Road. The 
specimen is, apparently, an Albino, 
and of the species Sand Martin 
(Hirundo riparia). The length and 
general appearance agree with the 
figure and description in Bewick. 
The colour is almost entirely white, 
but in one or two places there are 
shades of a brownish tint. I am in- 
formed that there are in the British 
Museum many white varieties of 
English birds; indeed, we have, 
most of us, seen, at times, partially 
white Sparrows, Starlings, Black- 
birds, &c.: but I have never before 
seen a White Martin, and I imagine 
such an almost purely white variety 
of any English bird is seldom seen 
as in the specimen shot by Mr. 
Wheeler.—T. Marsuatu,

Tur CrLoupep YrEttow (Colias 
Edusa). —'This rare and beautiful 
Butterfly has this year again ap- 
peared in our district. The only 
specimens we had hitherto seen from 
the neighbourhood of Wycombe 
were those in the collection of the 
Rey. T. H. Browne, by whom they 
were taken about five years since. 
Nine have been seen this year by 
different individuals, within our 
radius of five miles; and one was 
noticed near the Maidenhead station. 
The fact that only males have been 
observed in these instances suggests 
that they may have been in some 
manner introduced. The Clouded 
Yellow seems to be of more frequent 
occurrence this year than is usually 
the case: Mr. Ullyett states that 
it is very plentiful at Folkestone. He 
adds, ‘*I took a very fine specimen 
of the rare variety Helice in August 
last, a few miles from here. Although 
not in your locality, this note may 
prove interesting to the entomo- 
logiss.”’ 
PuospHoric CentTIprpsE,—Coming 
home rather late one night last 
August I saw on the Marlow Hill 
several of what I passed by as 
glowworms; but on stooping down 
to pick up one it moved away, and 
left a track of light behind it, both 
among the herbage and on the hard 
road. On seizing one, and boxing 
it, I found it tobe a centipede. My 
fingers were covered with the 
phosphorescence after handling it, as 
if I had been rubbing them with 
lucifers. Can you tell me the 
scientific name of this creature ? 
[No doubt it was Anthronomalus 
longicornis, figured in Wood's Nat. 
Hist., vol. iii. p. 693.—Ep. | 
THE WHEATEAR.—I have noticed 
this year during the latter end of 
March, the occurrence of the Wheat- 
ear (Saaicola Cénanthe). This 
species is not common in this neigh- 
bourhood, but in one walk I noticed 
four instances of it. According to 
Jardine, it is one of the earliest of 
our summer yisitants.
